BibTeX, biblatex and biber ⇒ Blocks, Colons, Commas and Periods in custom Style

[sjkiss]

Hi: I've got a custom .bst file that I've made using makebst. Everything is working fairly well, but I need to modify the punctuation that's setting off the blocks. I don't know if I can do this in the .dbj file or if I have to do this in the .bst file. The reference output is attached:

I need it to look like the following;
Rose, Jonathan. 2001. Title. Address: Publisher.
So everything is right, except for the punctuation after the author name and the dates. This needs to be uniform for articles, books, reports, etc.
Thank you!
Yours, SK

Hi: Ok, I was able to replace the comma after the year with a period, but now I need to replace the comma after the author. I did the first by altering one of the answers in the dbj file, but can't find a way to do the second in the same way.
